Our best-selling diaper, O.N.E, just got BIGGER and BETTER!  Introducing Big O.N.E., a diaper designed to meet the absorbency and size needs of larger kiddos. 

The Big O.N.E diaper is unique among cloth diaper all in ones (fits 35-70 pounds) because it comes with everything parents need to cloth diaper a larger toddler or older child. Enough absorbency to forget boosters and doublers (even overnight), two built-in closure options, and a heavy-duty construction that is built to last.

The Big O.N.E. features a unique Outlast closure system that gives you the ability to choose between Hook & Loop and Snap closures, and the ability to buy a replacement kit when your Hook & Loop wears out.

All with the same amazing quality you've come to know and love in GroVia products.

    O.N.E. Cloth Diaper - FAQ

    Before laundering, dispose of the solids. Remove the Outlast Closure Hook/Loop strips before placing Big O.N.E. in your diaper pail. We recommend removing Soaker Pads before placing them in the diaper pail so that each piece of the diaper is optimally agitated. Choose warm or hot water and enough of your favorite good-cleaning detergent.

    To cloth diaper full-time with the Big O.N.E. Diaper, you will spend between $600-$650. Remember that you’re saving 5x that by not buying disposables. To use the Big O.N.E. Diaper as your child's overnight cloth diaper, you will spend just over $100.

    For full-time cloth diapering, we recommend at least 24 diaper changes per child to best spread wear out among all the diapers in your supply.

    For using the Big O.N.E. as your child's overnight cloth diaper, we recommend having at least 4-6 as nighttime cloth diapers.

    An amazing product

    I LOVE big ONE diapers. No toxic materials and so comfortable. We have experienced no leaks. Some people complain that the children can’t have independence With taking them off and putting them back on, but my daughter just slides them down and slides them back up - although she is a thin child. The point of the diaper is because she doesn’t wake up in the middle of the night and so independence isn’t the priority right now, maybe it will be her nervous system develops little bit more. We are so happy we found this product and will be buying more. Thank you so much.

    Great product

    I love these diapers. My six year old still needs them at night and I never got cloth because I thought they’d leak: these do not. My daughter thinks they are very comfortable and we are very happy we are away from toxic materials once and for all. Thank you for creating such a great product

    Big kids can’t get it off at night

    I really wanted to like this because I have a big kid who can’t seem to wake up at night to go to the bathroom. But they have one HUGE flaw. My big kid can’t get it on or off by himself when he needs to go to the bathroom. Big kids need something easy on and off so they can have independence for potty time. I feel like I wasted my money on these. I don’t recommend for big kids who need to get them on and off themselves especially in the night.
